Aside from the Option modem I have a Huawei E160 around for testing:

ofonod[19115]: > AT+CRSM=192,12258\r
ofonod[19115]: < AT+CRSM=192,12258\r
ofonod[19115]: < \r\n+CME ERROR: SIM PIN required\r\n

Looks like it doesn't like the 'GET RESPONSE' either.

To be honest I have not the slighest idea what you mean :)

Well, if some one tells me what to do I work on it. But I'm a bit lost
without help.
